CD Bioparticles offers a comprehensive list of Quantum Dot Beads, which are made by embedding semiconductor quantum dots into amphiphilic macromolecules by self-assembly. Quantum dot beads as a new type of fluorescent labels exhibit significant advantages over common organic dyes, such as narrow, strong and tunable emissions, excellent photostability, good versatility in structure and component, and simplicity for excitation of multiple nanocrystals. In the meanwhile, by encapsulating a large number of quantum dots in microspheres, we can amplify the fluorescent signal of the quantum dots, reduce the biological toxicity of quantum dots, improve the biocompatibility and colloidal stability of the microspheres, and the microspheres can be coupled to other biological molecules through a variety of functional groups (such as carboxyl, amino, or streptavidin). https://www.cd-bioparticle...
